To all lwhom t may concern.' I

g Be it lmownthatvjl, CLAUS LnvINsEN, a

citizen ofthe Danish Monarchy, resident of Brooklyn, in the county of Kings and State Y of New York, haveinvented certain new andv useful Improvements in Steam-Regulating Valves, ofrwhich'theifol'lowmg 1s a specification. Y f

The object of my lnvention is to provide .an improved steam regulating valve especiallyV adapted for use' in marine steam power plants in order to improve the operation thereof with'respectjto safety, efficlency f and automatic action.

` Accordingly, my invention co'rnprisesl an improved steam regulating valve constructed and' operated asv hereinafter set forth, and

The valve comprises a valv'ejcasing 20 .j having an 'inlet 21 connected to the'auxiliary exhaust 15-16 and twooutlets 22 and 23 leading respectively to thek condenser 6 c and to the atmosphere 'by lWay of pipe 16.r The inlet 21fc'ommuncates with thevalve chamber 24 having the t'Wof` pQI'tsjZ and 26 leading to the outlet 22 and 23respectively, and controlled by the valves 27 land 28k respectively. "The`valve' 2 7 is provided with a sleeve 60 which extendstothe outside of the valve casing 20 through a stuffing box 61. Another 'stuHing box 62.l prevents leaks between the sleeve 60 and the valve spindle 29. The stuiing box 62V is adjusted byrotating a cap 63.` 64 is a nuton the'spindle and '65 isa spring' which urges thei'valve'27 upward to close'the ;port25. 'The upper valve 28 is provided'with a sleeve l3Ocwh'ich` g extends lto the outside ofthe Valve Casin 20 through astuiiing box 31'." Another stu g "box 32 prevents leaks between the sleeve 3() The diaphragm is held -inV position by a` member Y4:2 as shown. 113 is a spring which is 'secured to thexabutment VandY a plate 441ixed to the spindle29`and the'diaphragm '40 as shown.` The rspring therefore tends to 22 to the condenser. relative movement of the valve on dle 29 is provided for at 70.

` This condition only exists, however, so-

The running of the main engine with, consequently the diaphragm 40 lis pressed downward by atmospheric pressure which overcomes the lifting tendency of the spring 43 .causing the valve to assume the position shown in Fig. 2 which illustrates the'normal position with both ports 25a'nd 26' closed. E

Thus, the steam from the auxiliary machines-will pass through the valve to the condenser while the main engine is operating,` butA will be automatically shunted; Y through. the valve so as to pass tothe atmospherey (or auxiliary condenser) when the .main engine ceases to operate.
